CLEVI S.

SPECIFICATION forming part of Letters Patent No. 665,487, dated January8, 1901.

Application filed May 8, 1900.

T0 aZZ whom, it may concern.-

Be it known that I, HENRY O. TROWBRIDGE,

a citizen of the United States, residing at Millerton, in the county ofTioga and State of Pennsylvania, have invented a new and useful Clevis,of which the following is a specification.

This invention relates to draft appliances, and is especially designedto provide an improved clevis for application to plows and otheragricultural implements. It is furthermore designed to provide alongitudinally-yieldable device to relieve the strain from thedraft-animals instarting the implement or vehicle and to permit of alateral bending or flexing and also a twisting of the draft connection,so as to accommodate the latter to the varying movements of thedraftanimal.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereafter morefully described, shown in the accompanyingdrawings,and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure 1 is a side elevation of the improved clevis.Fig. 2 is a top I plan view thereof, and Fig. 3 is a longitudinalsectional view of the clevis.

Corresponding parts in the figures of the drawings are designated bylike characters of reference.

Referring to the accompanying drawings, 1 and 2 designate the oppositesides or members of the fixed portion of the clevis, which are designedto embrace the forward end of a plow-beam 3 or other draft-bar. Eachmember is in the form of a skeleton plate, which is provided withperforations 4 for the reception of suitable fastenings 5, whereby theplates may be secured to the plow-beam. The forward portions of theplates converge outwardly beyond the end of the plow-beam and areprovided at their outer extremities with corresponding eyes 6, which arenormally in engagement with each other.

Embracing the combined eyes 6 are the berial No. 15,928- (No model.)

I arms 7 of a subtantially U-shaped link 8, which is provided with aflat outer end, through which extends a longitudinal bore or opening 9.Fitted against the outer flat end of the link 8 is anotherreversely=arranged substantially U -shaped link l0,which has its arms 11provided with corresponding longitudinal slots 12, which are arranged atsubstantially right angles to the main slot of the link. This latterlink is also provided with a central bore or opening 13 to corre- 'spondwith the bore of the former link, and the combined bores are designed toreceive a connecting pin or bolt 14, which forms a swiveled connectionfor the two links. One end of the pin is provided with a fixed head 15,which is arranged Within the slot or bifurcation of either, link andbetween the head and the adjacent side of the link is provided a coiledspring 16, which also encircles the pin. The opposite end of the pin isprovided with a removable head in the form of a nut 17, and a coiledspring 18 embraces the pin and bears in opposite directions against thehead and the adjacent side of the link. By means of the removable headthe two links may be conveniently separated, and the springs permit ofalongitudinally-yieldable movement of the links upon the connecting pinor bolt.

At the outer end of the device there is provided a hook 19 forconnection with the draft animal or animals, and its rear end isprovided with the opposite arms 20, which are received Within thebifurcated portion of the outer link and are connected thereto by meansof suitable fastenings 21. It will of course be understood that the armsof the inner link 8 are pivotally or hingedly connected to theclevis-plates by means of a suitable pivot-pin 22, which passes looselythrough the eyes 6 of the plates.

From the foregoing description it will be seen that the draft connectionhas a vertical movement in opposite directions upon the hinged jointformed by the pivot-pin 22. The

hook and the outer link are longitudinally and elastically yieldableupon the connecting pin or bolt and also may be twisted, by reason ofthe swiveled connection between the two links, whereby the device iseffectually arranged to accommodate itself to the various movements ofthe draft-animals, and thereby relieve the latter of considerablestrain.

What is claimed is 1. A draft appliance, comprising a clevis or fixedmember for application to a plow-beam or the like, a pair of links whichare mutually swiveled together, one of the links having a hinged orpivotal connection with the clevis, and a hook connected to the otherlink.

2. A draft appliance, comprising aclevis or fixed member for applicationto a plow-beam or the like, a pair of links having correspondingopenings, a bolt 0r pin loosely received within the correspondingopenings, and provided with heads at its opposite ends, coiled springsencircling the pin and bearing in opposite directions against the headsand the adjacent links, and a hook connected to the outer link.

3. A draft appliance, comprising a clevis or fixed member forapplication to a plow-beam or the like, a substantially U-shaped linkhaving its arms pivolally connected to the clevis, a secondreversely-arranged substantially U-shaped link, a swivel bolt or pinconnecting the links, coiled springs encircling the opposite endportions of the pin or bolt and bearing in opposite directions againstthe pin and the adjacent links, and a hook, having a pair of arms thatare secu red within the bifurcation of the outer link.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

HENRY O. TROWBRIDGE.
